What is the analysis of bioelectric impedance?
Bioelectric impedance analysis (BIA) is a simple, quick way to calculate the estimated body fat. In the analysis of bioelectric impedance, the body of the test entity passes a very low electric current. Indeed, BIA monitors measure overall body water in the human body.
The total number of body water is used to calculate body mass without fat. The weight of the lean body is then subtracted from the weight of the subject of the test subject. The rest is the total body fat.
body fat measurement is expressed as the total body weight index (BMI). BMI indicates the ratio of lean muscle to body fat. BMI 18.5 to 24.9 is generally considered normal.
If BMI is below 18.5, this person may be underweight. In general, BMI 25 to 29.9 means that the test entity is overweight. BMI 30 or higher usually shows obesity.
To complete the analysis of bioelectric impedance, the impedance of a small current passing through the body is measured. Water Vedets Electricity and is located in TThe rumor body. Body fat or fat tissue , does not contain any water and is a poor conductor of electricity. As a result, lean body mass will have lower impedance than body fat.
The amount of current used in BIA is so small that the test subject will not feel it. In the United States of the National Institute for Health, it concluded that the electric current used in BIA is generally safe for most people. The conference statement noted that no testing, better known as pacemakers, has been completed in people with implanted cardiac defibrillators.
Together with impedance measurements, other factors about the test entity are needed to calculate BMI. This includes physical information such as height, weight, body type, ethnicity and age. Lifestyle information such as exercise levels and overall health is also required.
several other factorsS can change the result of the analysis of bioelectric impedance. The current level of hydration and skin temperature can change the test results. The lying test can have different results than the test completed with the person getting up.
BIA monitor types include hand versions and scales. These portable options have been widely available from the 80s. Previous versions of these commercially available BIA models were considered unreliable.
Technological improvements allow today's monitors of bioelectric impedance analysis to provide more accurate results. Portable models are commonly found in health clubs and can easily be purchased by individuals. More complex models that connect electrodes to hands and legs usually occur in a medical office or in another professional environment.
